Senior Full Stack Software Development ServicesDevelopment Services
We build your product with senior engineers only. Fixed pricing delivered in 8-12 weeks.
IRPR builds senior full stack software development services for companies that need production-ready web apps, mobile apps, and APIs. Our engineers use React, Next.js, Node.js, Python, and AWS to ship code that scales from day one.
Every project follows our fixed-price model: we scope the full build during a 1-week Roadmap phase. Timelines run 8-12 weeks for an MVP with pricing from $80K to $250K depending on complexity. We handle HIPAA, PCI-DSS, and SOC 2 compliance out of the box.
Our clients are CTOs who need to scale an engineering team without hiring, founders who want a technical co-founder to build their MVP, and enterprise leaders who demand compliance and security from the first commit.

Senior full stack software development services trusted by 200+ products
Every project ships with the same process that has delivered for clients in 50+ countries.
IRPR has shipped over 200 products across healthcare, fintech, and ecommerce. Our senior full stack software development services follow a repeatable 4-phase process: Idea, Roadmap, Product, Release. This structure keeps projects on time and within budget.
We assign 2-4 senior engineers per project. No junior developers. Our average engineer has 10+ years of experience. This is why 98% of our projects deliver on time and every client gets full code ownership.
How we differ from generic development shops
Most agencies promise senior talent but deliver juniors. IRPR puts senior engineers in front of your code from day one.
When you hire a generic dev shop, you often get project managers writing vague user stories and junior developers writing code. Budgets run over. Deadlines slip. Compliance is an afterthought.
IRPR works differently. Every project starts with a senior engineer scoping the work during the Roadmap phase. You get a fixed price, a fixed timeline, and a dedicated team that writes production-ready code.
- Junior developers on your project
- Hourly billing with no cap
- No QA until launch week
- Security review is an extra fee
- No documentation delivered
- Code ownership unclear
- Senior engineers only (10+ yrs avg)
- Fixed price from Roadmap phase
- Dedicated QA throughout build
- HIPAA/PCI/SOC2 compliance built in
- Full documentation and runbooks
- You own 100% of the code
The senior full stack development process in 4 phases
Each phase has a clear output. You see progress every week.
We follow a structured process that has been refined over 200+ projects. Every phase ends with a deliverable you can review, test, and approve before moving forward.
The total timeline for most MVPs is 8-12 weeks from Roadmap approval to production launch. Larger platforms with multiple integrations may extend to 16 weeks.
What ships with every senior full stack engagement
You get more than a running app. You get a complete system you can maintain and grow.
Every project includes the full source code, infrastructure-as-code, and a runbook that lets your team take over immediately. No black boxes.
We also include automated tests, CI/CD pipelines, and performance reports. This is standard, not an upsell.
- Full source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions or AWS CodePipeline
- Automated unit and integration tests (80%+ coverage)
- Deployment to AWS/GCP with Terraform or CloudFormation
- Error monitoring with Sentry and performance with New Relic
- API documentation (OpenAPI/Swagger)
- User documentation and admin guide
- Post-launch support for 30 days (bug fixes only)
- Performance and security reports

Most MVPs ship in 8-12 weeks. We use proven templates and CI/CD automation to eliminate wasted time. Your product is live, not stuck in development.
You own all the code
Full source code, all documentation, and infrastructure scripts are yours. No licensing fees. No vendor lock-in. You can walk away with everything at any time.
Compliance built from day one
HIPAA, PCI-DSS, SOC 2, and FERPA are part of our standard stack. We include audit logs, encryption, and access controls in every project.
Post-launch support included
Every project includes 30 days of post-launch support for bug fixes and monitoring. After that, you can continue with a maintenance retainer or take over yourself.
